Fused polycyclic nitrogen-containing heterocycles : 1116. Selenazolo[3,4-a]-and thiazolo[3,4-a]quinoxalin-4(5H)-ones

Upon treatment with acetic acid, 3-(2-phenyl-1-selenocyanatoethyl)-, 3-(3-phenyl-1-selenocyanatopropyl)quinoxalin-2(1H)-ones and their thio analogs undergo intramolecular condensation to form selenazolo-and thiazolo[3,4-a] quinoxalines.

A new facile, efficient synthesis and structure peculiarity of quinoxaline derivatives with two benzimidazole fragments

A highly efficient and versatile method for the synthesis of quinoxaline derivatives with two benzimidazole fragments have been developed on the basis of the ring contraction of 3-(benzimidazo-2-yl)quinoxalin-2(1H)-one with 1,2-diaminobenzene and its various types of substituted and condensed derivatives. Owing to the inter- and intramolecular processes, involving self association, proton exchange, conformational, and/or tautomeric exchanges between several forms for most of the bis-benzimidazolylquinoxalines signals of bridged and neighboring carbon atoms and the hydrogen atoms of the neighboring carbon atoms of benzimidazole fragments in the NMR spectra are broadened. The conjugation between the benzimidazole fragments and the quinoxaline core of the molecules is increased from the quinoxaline derivative (10c) to its thiadiazol[f]- (17) and pyrrolo[a]-(19) annulated derivatives, resulting in a greater planarity of the molecule as a whole.

Darzens reaction in the synthesis of 3-(α-chloroalkyl)quinoxalin- 2(1H)-ones

A two-stage method was developed for the synthesis of 3-(α- chloroalkyl- and α-chlorophenylalkyl)-quinoxalin-2(1H)-ones proceeding from methyl chloroalkyl- and chlorophenylalkylpyruvates obtained by Darzens reaction from methyl dichloroacetate and appropriate aldehydes in the presence of t-BuOK.
